This function verifies if the difference in dates within each date in the provided observations corresponds to the provided timestep. This check is performed for both report_date and reference_date and for each group in obs.

Usage

check_timestep_by_date(obs, timestep = "day", exact = TRUE)

Arguments

timestep

The timestep to used. This can be a string ("day", "week", "month") or a numeric whole number representing the number of days.

exact

Logical, if TRUE``, checks if all differences exactly match the timestep. If FALSE``, checks if the sum of the differences modulo the timestep equals zero. Default is TRUE.
